Piggybacking on the midframe, we find the Touch ID Nexus Imprint fingerprint reader.

Google claims Imprint can recognize a fingerprint in just 600 ms—quick enough to skip the lock screen entirely.

Flipping the Imprint over reveals an unidentified control chip and our favorite, spring contacts! These connectors are much more durable than traditional connectors that snap into place, and they're much easier to work with during repairs. Win win!
